# Low-level programmig
Personal project to lean low-level coding inspired by the book: [Low-level programming: C, Assembly and program execution on Intel 64 architecture](https://www.apress.com/br/book/9781484224021) - by Igor Zhirkov.
The official GitHub of the book can be found [here](https://github.com/Apress/low-level-programming).
Besides these original idea, this project turned into an opportunity to learn more about git, makefile, GNU GDB, GNU GCC and OS principles.

## Environment
### Operating System
- Fedora 31 x86_64
- Linux kernel: 5.8.18-100
### Programs used
* __C compiler__: GCC Red Hat 9.3.1-2
* __ASM compiler__: NASM 2.14.02
* __Debugger__: GNU GDB 8.3.50.20190824-30.fc31
* __Make__: GNU MAKE 4.2.1
## Usage
### Makefile
#### 1. Assembly
In the `assemblyfiles` directory:
- Compile all the `.asm` files and create the `bin/` and `build/` directories.
```bash
make -s
```
- Compile that specific `.asm` file
```bash
make bin/file_name -s
```
- Clean all the binaries
```bash
make clean
```
- Create GDB setup and commands shortcuts for debugging
```bash
make gdb
```
The `-s` flag hides the commands that are executed.
[GNU Make manual](https://www.gnu.org/software/make/manual/make.html).
---
#### 2. C language
In the `cfiles` directory:
### GNU GDB
All the layout and initial configuration is done by the commands written in `~/.gdbinit` and `assemblyfiles/bin/.gdbinit`.
Besides that, all the commands can be found in [GNU GDB documentation](https://www.gnu.org/software/gdb/documentation/).
